Cloud-native applications are designed and developed differently than traditional on-premise or virtual machines and require new security considerations. In this article, we will discuss the security challenges of modern cloud-native apps, such as the speed of changes, restricted visibility, networking, configuration flaws, poor code quality, and open-source vulnerability. To protect modern apps, a multi-layered security strategy is required that covers all levels of the application’s components. The first layer of this strategy is posture management, which includes constant security scanning of platform configuration and code. The second layer is strong network security that creates network security within the container or serverless application. Cloud firewalls and network plugins such as Cilium CNI can help protect cloud-native apps. A comprehensive security approach, such as the Cloud-Native Application Protection Platform (CNAPP) from Prisma Cloud, can also improve cloud security posture.
